GROUP # coaster track: At this point you've gotten as far as you can without actual numbers. Let's set up an example roller h m The designers have set the height h of the coaster's first hill to 75 m, and the length L of the hill's curved track is 180 m. The empty cart (without people) has a mass of 600 kg. Additionally, the designers have determined that the empty cart feels a total resistive force of 60 N as it travels along the track, due to the interaction between the cart and the track, and interaction between the cart and the air. Using any of these values that go into your energy model, determine the launch velocity of the cart, in m/s, that is the slowest possible speed and still have the cart reach the top of the hill: me booky EK + Ey ; E ER ATOF 9 : 7. 8 m / s 2 h= 75 m Workshop 3: Energy II Group Worksheet | Page 6 of 12
